发明名称 Multi-radio terminals with different intermediate frequencies
摘要 Terminals with multiple radio units employing different IF frequencies for RF to IF frequency downconversion are provided. Each radio unit is operative to process a respective input signal with a respective LO signal to provide a respective IF signal having a desired IF component at an IF frequency selected for that radio unit. The input signal for each radio unit includes RF components at different RF frequencies. The desired IF component for each radio unit corresponds to a downconverted version of one of the RF components in the input signal. The IF frequencies for the radio units are selected such that the desired IF components for these radio unit do not overlap one another in frequency. The IF frequencies may be selected such that, for each radio unit, the undesired IF components fall outside of the IF passband selected for that radio unit and may thus be filtered out.
